You're right to point at the backs as being where Ireland were a lot bigger but I think you might just have been massively racist and thought Joseph and Burrell are the same person ^_^ Joseph's only 90kg, the joint smallest man in either side's three-quarters. Burrell's 104kg and the biggest.
The English pack is slightly larger, but only slightly; Ross, McGrath and Toner nearly counterbalance a very scrawny back row.
